Russia's full-scale invasion began 24 February 2022, following eight years of lower-intensity conflict after the 2014 Crimea annexation. A contentious Oval Office meeting in February 2025 marked a new phase in the diplomatic effort to end it. Here is the essential background.
By 2026, coverage of the Ukraine conflict has largely shifted toward diplomacy, front-line status and the search for an eventual settlement — but understanding that current phase requires the background that shaped it. The war did not begin in February 2022, and the diplomatic dynamics playing out now, including the shift in US-Ukraine relations that became publicly visible in early 2025, are shaped directly by decisions and events stretching back over a decade.
Ukraine's 2014 Euromaidan revolution — mass protests that removed a Russia-aligned president following his rejection of a planned EU association agreement — triggered the conflict's first phase. Russia responded by annexing Crimea and backing separatist forces in Ukraine's eastern Donbas region, sparking a lower-intensity war that killed an estimated 14,000 people over the following eight years, largely out of sustained Western media attention despite its severity.
Russia's full-scale invasion began on 24 February 2022, launched from multiple directions simultaneously: from Belarus toward Kyiv, from Russia's north-east border, and from the existing front lines in Donbas and Crimea. The initial assault on Kyiv failed against unexpectedly effective Ukrainian resistance, and Russian forces withdrew from the region by early April 2022. The war then settled into a grinding, attritional conflict concentrated primarily in eastern and southern Ukraine — a pattern that, with periodic shifts in front-line position, largely continued through the following years.
| Phase | Period | Key development |
|---|---|---|
| Pre-invasion conflict | 2014-2022 | Crimea annexation, Donbas separatist war (~14,000 deaths) |
| Full-scale invasion, initial phase | Feb-Apr 2022 | Failed assault on Kyiv, Russian withdrawal from the region |
| Attritional phase | 2022-2024 | Front-line conflict concentrated in eastern/southern Ukraine |
| Kursk incursion | Aug 2024 onward | Ukrainian forces occupy Russian territory for the first time since WWII |
In August 2024, Ukrainian forces launched a cross-border incursion into Russia's Kursk region, seizing and holding Russian territory — the first foreign occupation of Russian soil since the Second World War. Military analysts widely interpreted the operation as serving two purposes: diverting Russian forces away from pressure points on the eastern front, and creating a potential bargaining asset — occupied Russian territory Ukraine could offer to trade — for any future negotiation.
That negotiation dynamic shifted visibly in February 2025, when a meeting between President Trump and President Zelensky in the Oval Office, intended to discuss a proposed US-Ukraine minerals and security arrangement, became publicly contentious, with a heated on-camera exchange reported across international media. The episode marked a genuine, visible change in tone in US-Ukraine relations compared with the consistently supportive posture the Biden administration had maintained since 2022, and it fed into a broader, actively evolving US-led diplomatic effort through 2025 to bring the parties toward some form of negotiated resolution.
"The war's trajectory has always been shaped as much by what happens in Washington, Brussels and Moscow as by the front line itself. 2025 made that more visible than at any point since the invasion began." — a framing widely echoed across foreign policy analysis following the shift in US diplomatic posture from early 2025 onward.
For UK and European readers, the conflict's most direct lasting effects are already structural rather than hypothetical. Germany's commitment to meeting NATO's 2% of GDP defence spending target — a genuinely historic shift for a country that maintained comparatively restrained defence spending since 1945 — is one of the clearest examples, alongside a broader, sustained increase in European defence spending commitments more widely, discussed in more detail in our coverage of NATO's changing defence posture. The EU's rapid move to reduce dependence on Russian gas imports has also reshaped European energy policy and pricing in ways likely to persist regardless of how or when the conflict itself is eventually resolved, with effects that have fed directly into UK and European household energy costs since 2022.
Ukraine's domestic economy and society have also been reshaped by the war in ways that will outlast any settlement. Millions of Ukrainians have been displaced internally or fled abroad since February 2022, straining housing, labour markets and public services in host countries across the EU and beyond, while inside Ukraine, wartime conditions have forced rapid adaptation in areas ranging from domestic drone manufacturing to decentralised energy generation, following repeated Russian strikes on national power infrastructure through successive winters. Understanding the conflict's background, then, means understanding not just the military and diplomatic timeline but a genuinely society-wide transformation whose effects — on population, infrastructure and economic structure — will shape Ukraine, and its relationship with European neighbours, for a generation regardless of exactly how or when the active fighting itself concludes, and regardless of the precise terms any eventual settlement ultimately takes.
Given how fluid the diplomatic situation has remained since the February 2025 Oval Office meeting, the most useful thing to track is not any single predicted outcome but the ongoing negotiation dynamics between the US, Ukraine, Russia and European allies, whose alignment has shifted meaningfully more than once since the invasion began — for the latest on where negotiations and front-line status actually stand, see our regularly updated Ukraine war status coverage. Also worth watching: whether the reshaped European defence spending commitments triggered by the conflict prove durable once any eventual resolution reduces the immediate sense of threat that drove them, a question with direct implications for UK defence spending decisions specifically.
